Running for nine years, it's the only festival in Norway for house and techno and takes place in Ekebergsletta, an epic, grassy hillside spot in Oslo. The Main Stage will be the place for house music, while the Hangar Stage is where you'll find techno.

Don't just expect the usual festival programming. There will be a B2B marathon, bringing Norwegian DJs together for a collaborative set, and they'll be looking to trump the 17 that played together last year.

Fan of art? That's all taken care of, too, as there will be exhibitions, installations and performances, with 10 artists and collectives showcasing work. There's also the Knowledge programme which delivers panel debates, lectures, workshops and viewings.

Sweden's Sebastian Mullaert said: "I'm super happy to be back in Oslo and play an extended long live improvisation at the amazing Sommerøya festival".
